Mechanical Superfine Grinding

The impact classifier mill ICX is perfectly suitable for energy-efficient, dry superfine grinding. Based on the proven NEA ICM impact classifier mill technology, NEA Process Technology developed the impact classifier mill ICX to address the specific challenges of supefine grinding. In particular the grinding intensity via specifically designed grinding tools as well as the air and product guidance were optimized within the mill, enabling an efficient superfine grinding and classifying process.

ICX - Highly efficient classification, precise, flexible, energy-saving

The NEA ICX enables energy-efficient grinding in areas of fineness hitherto reserved for jet mills and ball mills. This now enables the realization of finest grinding in a compact, energy-saving grinding system, which does not require any additional aggregates such as air compressors.

The typical ICX classifier mill applications are in the areas of chemicals, pigments, food, cosmetics and pharmaceuticals.

Easy Operation and Cleaning of the Classifier Mill

In addition to optimization for finest grinding, NEA Process Technology has taken over the ease of operation and good maintainability of the proven impact classifier mill ICM.

Thus, the ICX is also available as a pressure shock resistant model for grinding potentially explosive dust such as sugar, carbon black etc. and can therefore easily be integrated into ATEX-compliant systems.
